Obstetrics and gynecology is a discipline dedicated to the broad, integrated medical and surgical care of women's health throughout their lifespan. The combined discipline of obstetrics and gynecology requires extensive study and understanding of reproductive physiology, including the physiologic, social, cultural, environmental and genetic factors that influence disease in women. This study and understanding of the reproductive physiology of women gives obstetricians and gynecologists a unique perspective in addressing gender-specific health care issues.

Preventive counseling and health education are essential and integral parts of the practice of obstetricians and gynecologists as they advance the individual and community-based health of women of all ages.

Obstetricians and gynecologists may choose a scope of practice ranging from primary ambulatory health care to concentration in a focused area of specialization.
